Step-by-step explanation:

Use Euler's Theorem: V-E+F=2

F=12

E=18

V-18+12=2

V-18=-10

V=8

So there are 8 vertices

1. Find the probability of this set of independent events. rolling a six on the first roll of a 1-6 number cube and rolling an o
jeyben [28]
For the first question, the chance of rolling a six is a 1/6 chance because there is one six and six different sides that could be rolled. As a percent, it would be 16.6 %. The probability of rolling an odd number on the second roll would be a 3/6 chance, which as a percent is 50 %. For the second question, both probabilities are 33 % because in both instances you are drawing three cards from nine total, so it would be 3/9. For the third question, the probability of drawing a blue marble is 3/5, because there are three blue marbles and five total marbles. As a percent, this is 60 %. Following this up with a green marble would be 2/4, because there are now 2 green marbles and four total marbles. One of the marbles was not replaced, so we have one less marble. 2/4 as a percent  is 50%.
